MOPED ARMY

setup please....

example:

50v

av10

70cc kit

15:15 carb 90 jet

ninga pipe

bidalot variator

JATO rocket

NOS

Boostbottle

etc.

u get it

ha no shit

50v

av10

stock clutch with malossi varriator

dellorto 16mm sha 66 jet

carbon fiber reeds (don't know what kind)

Bidalot 50cc kit with HC head

15mm 90degree intake

Doppler Pipe

18 pack of PBR

I noticed that it doesn't really seem to be pulling air through the carb when it is running but I can hear it sucking when I turn it by hand. I am worried that the kit is done, the crank was beat to shit and so were the bearings but I am trying to be optimistic, the cylinder walls look clean and the piston has been sanded a little but not extensively.

I checked the plug and it is real wet with a nice black but not fouled electrode and the insulator is still white.

When I mean no power I mean it idles alright but goes about 1-2 mph at all throttle positions and won't rev at all.

70psi is pretty much non-running. A good version of that kit would be getting 175 psi. However, your compression tester might be at the end of its rope.

Yeah, thats not going to work so well. Can you try holding it while you go down a hill?

Has anyone ever tried to put rope or something on the flywheel to turn over a moby I might try that when I get back to the squid garage.

Nope It opens all the way and it runs differently when you give it throttle just doesn't rev unless the wheel is off the ground oh I forgot to add that part.

whats the deal with your timing?

that jet is probably also too small.

62(?) is what i was running on a 15.15 dellorto on an otherwise stock moby.

upjet at least 20 and go from there, that bidalot kit moves some serious CFM.

Also av7 bottom end completely including points.

Well obviously an av10 case. Checked the timing, about 1.5 btdc gapped to .021, exhaust is brand new ran it for about a month.

When it is on the stand it dogs for a second then it revs like crazy. But when it's on the ground it is a complete dog and bill bog down and stall if I hit the throttle too fast.

I took the plug out after and looks a little light but still in the dark tan range. Also there is an awful lot of unburned fuel coming out the pipe.

Internals are quiet as far as I can tell except the variator makes a little humming type noise which it made before. Tried to get a better compression reading but I need a different tester.

Well I am giving up for the night any Ideas would be great for the morning.

yeah how it starts can often explain alot.

also spray the carb cleaner around and check 4 leaks it sounds like u may have a few.

often you will need to use some rtv sealant in the reed block setups to solve leak issues.

I started checking for leaks last night but didn't finish. Other than being real hard to push start without a decomp is starts good. Once I get it to turn over it starts right up and idles like a champ. When I put it together I did notice it looked like there was thick sticky stuff looks like old black rtv on the reedblock but only on the triangle sides where the reeds don't touch so I didn't think much of it.. The reeds also appeared to sit flush with the metal and they were flexible and snapped back when you lightly pull on the bottom.

The head uses an o-ring instead of a gasket to seal so I might try replacing that as well with a gasket, but there doesn't appear to be any fuel seeping out between the cylinder and head so it might be alright.

on my av7 i was having a similar problem couldnt get above 8mph or so. it turned out there was a tiny crack in the case and i was loosing just enough compression. if you can keep it idleling, then use soap and water and see if theres any leaks on the case itself.

av10's usually dont have timing, the CDI ones are fixed.

there are av10's with points though.

im suggesting changing the timing based on the way the bidalot kit is most likely ported (somewhat similar to doppler 50 probably)
